- *A rewrite of [this SE question](https://codegolf.stackexchange.com/questions/16124/write-an-interactive-deadfish-interpreter) with a simpler input format and guidelines.*
- ## Challenge
- Deadfish uses a single accumulator, on which all commands are to be performed.
- It has the following commands:
- |Command|Description
- |-|-
- |`i`|increment the accumulator
- |`d`|decrement the accumulator
- |`s`|square the value of the accumulator
- |`o`|output the value of the accumulator as a number
- If, after executing a command, the accumulator is equal to -1 or equal to 256, the accumulator must be reset to zero.
- ## I/O
- Input can be taken as a single string, list of codepoints, or any other reasonable format. It is guaranteed that the input will only consist of deadfish commands.
- Output can be given as an array of numbers, or just the numbers printed with separators between them.
- ## Testcases
- (some are borrowed from the [Esolangs wiki](https://esolangs.org/wiki/Deadfish#Mandatory_test_cases))
- ```
- iissso -> 0
- diissisdo -> 288
- iissisdddddddddddddddddddddddddddddddddo -> 0
- isssoisoisoisoiso -> 1,4,25,676,458329
- ooooosioiiisooo -> 0,0,0,0,0,1,16,16,16
- iiii -> nothing
- iiiiiiiissdiiiiiiiiiiiiiiiiio -> 4112
- o -> 0
- ```
